ethabi

ABI（应用程序二进制接口）基本上是调用合约函数并获取数据的方式。

ABI决定了诸如函数如何调用以及信息应以何种二进制格式从一个程序组件传递到下一个程序组件等细节...

以太坊智能合约是字节码，EVM，位于以太坊区块链上。在EVM中，一个合约中可能有几个函数。ABI是必要的，这样你就可以指定调用合约中的哪个函数，以及确保该函数将以你期望的格式返回数据。 了解更多

此库编码函数调用并解码它们的输出。

免责声明

本库旨在仅支持由最近版本的Solidity生成的有效ABIs。具体来说，我们不打算支持由于已知的Solidity漏洞或外部库不严格遵循规范而变得无效的ABIs。请在使用ethabi之前确保预处理您的ABI，以防其不受支持。

安装

cargo install ethabi-cli
